Whether the textile industry uses disposable or gauze masks, it is not scientific protection.
The state has issued a document that gauze masks cannot be used as dust masks. Some disposable masks have a high certification level, such as N95 level, but in the national standard, it has been stipulated that the protection level of disposable masks is only obtained by the recommended filter elements, and for the fit between the mask and the face, only the air leakage rate is less than 13% is considered qualified. That is to say, N90 and N95 masks, in addition to the leakage of 5-10% of the filter cotton itself, also leaked about 10% of the dust from the mask, resulting in haze, high dust and other environments, and the actual protection effect is poor.
In the textile industry, for the health of employees, it is recommended to choose a replaceable filter N95 N100 grade dust mask. While ensuring the protection effect, it can effectively reduce the cost of protection.
1. As a special labor protection article, the dust mask must be certified by GB2626-2006 "Self-priming Filtering Anti-particulate Respirator".
2. Masks are divided into disposable and replaceable filter half masks and full masks. In dusty environments, it is recommended to use a replaceable cotton filter half mask.
3. The mask material is silicone, plastic, etc., and the silicone material is relatively soft and comfortable, and the pressure sensitivity is low.
4. For the smoke and dust in the environment, use a dust mask (can be prevented: dust, smoke, fog, microorganisms). There are three levels of protection level: KN100, KN95 and KN90, the smoke and dust concentration in the working environment is high, and some contain a large amount of silica, so it is recommended to choose KN100 level.
5. It is particularly important that the mask is divided into sizes according to the national standard. Masks are not semicolonized, and the effect will vary from person to person.
6. There are two types of masks: covering the mouth and nose and covering the mouth, nose and jaw, of which the second type has a large contact mask, good sealing and low pressure sensitivity.
7. Choose one with low breathing resistance. The national standard stipulates that the inhalation resistance is 350 Pa, and some are only about 120 Pa, so breathing is smooth. Masks with high breathing resistance are easy to cause damage to the lung diaphragm.
Through the above methods, the choice of KN100 mask can effectively prevent the occurrence of respiratory tract and lung diseases.

1. The production process and materials are differentMedical masks are mostly made of one or more layers of non-woven fabrics, and in general, disposable ordinary non-woven masks are mostly made of some non-woven fabrics. And the production process is also different, the production process of medical masks includes meltblown, spunbond, heat sealing or acupuncture, etc., which has the effect of resisting liquids and filtering particles and bacteria.
2. The effect of use is different:Ordinary non-woven masks do not filter particles in the air. However, medical masks can effectively isolate particles in the air, and the effect is also relatively good for preventing some diseases spread by droplets.
3. **Different:Microfiber masks have a higher ** than non-woven masks.
Precautions: In order to better play the protective role of the mask, try to tighten the elastic band of the mask when wearing the mask, and press the aluminum sheets on both sides of the nose to reduce the leakage around it, and it is best to breathe slowly.
Wear it at the right time. The medical non-woven mask can be used for 6-8 hours, and should be replaced in time in case of the following conditions: difficulty breathing, the mask is damaged or damaged, the mask cannot fit well with the face, the mask is contaminated (such as when it is stained with foreign objects such as blood stains or droplets), has been used in the isolation ward or patient contact, and has peculiar smell.

The non-woven mask focuses on filtration efficiency, flame retardant performance, disinfection, sterilization, and dustproof. Advanced microfiber material filters particles over 1 mIdeal for the filtration of dust, bacteria, allergies, smoke, pollution, dust, pollen, advanced microfiber materials can filter particles of more than 1 m.

1. Disposable masks are non-woven fabrics, which are generally made of more than 28 grams of non-woven fabrics with three layers, which have very good air permeability, can filter toxic gases, and have a relatively light texture, but the fabric is more fragile than masks made of other materials, so you must pay attention to it when using it.
2. The disposable three-layer mask is made of two layers of fiber non-woven fabric specially used for medical and health care, and a layer of filter paper is added in the middle through ultrasonic welding, which has very good air permeability, can filter toxic gases, and has a relatively light texture, but compared with other fabrics, disposable masks cannot be cleaned and are easy to be torn apart, so we must pay attention when using them.

Which is better, gauze mask or disposable mask, mainly depends on the use.
Gauze masks are usually suitable for preventing low concentrations of harmful gases and vapors, gauze masks can be used repeatedly, and gauze masks must be cleaned and disinfected before they can be reused.
Disposable medical protective masks can generally isolate those droplets and blood in the air, and can also be used to isolate those body fluids or secretions in the air. To sum up, it is better for industry to use gauze masks; In terms of virus prevention, disposable masks are still better than gauze masks.
No. Gauze masks are generally used in industry, and medical masks include: disposable medical masks, medical surgical masks, medical protective masks and KN95 N95 and above particulate matter protective masks.
Tips: It is recommended to pay attention to the reasonable and standardized use of masks and pay attention to cleanliness and hygiene in order to effectively protect against the virus.
It has a certain effect, but the effect is not as good as that of professional medical masks.
Medical masks have different functions of isolating bacteria and viruses according to the category of masks, and non-medical masks basically have no effect of isolating viruses and can only block droplets.
Blocks harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose.
Gauze mask is a kind of hygiene product, generally refers to the use of the mouth and nose to filter the air entering the mouth and nose, in order to block harmful gases, odors, droplets in and out of the wearer's mouth and nose, gauze masks are usually made of gauze or paper and other materials, the use of gauze masks has a certain filtering effect on the air entering the lungs.

1 is not very good.
The general gauze mask has cotton in it, although it has a certain protective effect, but it does not have much effect on small particles such as bacteria and viruses, and is only suitable for those low-risk exposed people.
2. Disposable masks are better.
Disposable masks are generally made of non-woven fabrics, which are electrostatically treated, which can not only block large-diameter particles, but also have a good effect on the protection of fine particles; The material of the gauze mask is some mechanical fabric, which only has a certain effect on large-diameter particles.
The disposable mask is very thin, which greatly reduces the user's breathing resistance, and the nose clip above the mask can make the mask fit well to the face, which can achieve better isolation efficiency. The gauze mask is thicker, and there is a lot of breathing resistance on the human belt, and the airtightness with the face is not good.
3 Yes. Gauze masks are mainly made of gauze as raw materials, which can be washed, and can be continued to be used after cleaning, gauze masks can be gently washed with water and soap, but it is necessary to pay attention not to use excessive force, the gauze mask may be broken, and then disinfected and dried, generally gauze masks can be cleaned 3-7 times, but gauze masks should not be used after they are damaged.
4. The use time of gauze masks should be determined according to the environment and human condition.
If the environmental pollution is serious and there are more particles in the air, after a period of use, there will be a lot of larger particles attached to the gauze, so the mask should be replaced in time; If you wear a gauze mask and experience increased breathing resistance and discomfort, it is also recommended to change the mask.

Both textile pigments and acrylic paints have specialized seasonings, which are liquids used to mix pigments. The properties of the spice can maintain the properties of the pigment, strengthen the firmness of the pigment on the clothing, and ease the drying time of the pigment. Textile pigments must be seasoned, its own pigment adhesion is not as good as acrylic pigments, in order to keep the pigment on the clothing for a longer time, so textile seasonings must be used. >>>More
